gpio: wcd934x: mark the GPIO controller as sleeping

Bartosz Golaszewski · Bartosz Golaszewski · commit b5f8aa8d4bde · 2025-10-10T09:37:19.000+02:00
The slimbus regmap passed to the GPIO driver down from MFD does not use fast_io. This means a mutex is used for locking and thus this GPIO chip must not be used in atomic context. Change the can_sleep switch in struct gpio_chip to true. Fixes: 59c3246 ("gpio: wcd934x: Add support to wcd934x gpio controller") Signed-off-by: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>
